2 1. Introduction These Application Notes describe the configuration of a Voice over IP (VoIP) solution using ProCurve 5400, 3500, 2910 and 2610 Series Switches by HP with an Avaya Telephony Infrastructure consisting of Avaya IP Office and Avaya IP telephones. Compliance testing emphasis was placed on verifying the prioritization of VoIP traffic and voice quality in a converged VoIP and Data network scenario. Quality of Service (QoS) based on Layer 2 Priority (802.1p) and Layer 3 Differentiated Services (DiffServ) was implemented across the network to prioritize voice traffic over the LAN. The Avaya IP telephones get QoS priority settings from Avaya IP Office and are enforced in the network by the ProCurve Switches. The VoIP traffic was given priority over data traffic, tests were performed by over-subscribing the LAN interfaces with low priority data traffic and verifying that acceptable voice quality was achieved when calls were routed over all of the LAN interfaces. Compliance testing included testing QoS, throughput, link aggregation, rapid spanning tree, load balancing, Open Shortest Path First (OSPF), and Direct IP Media connectivity while using G.711 and G.729 codecs Interoperability Compliance Testing Interoperability compliance testing covered feature functionality, serviceability, and performance testing. QoS testing verified that when the ProCurve Switch interfaces are over subscribed with low priority data traffic, the higher priority VoIP media and signaling traffic still got through and achieved good voice quality. Prioritization of voice traffic was achieved by implementing Layer 3 DiffServ-based QoS and Layer 2 priority (802.1p). Voice and data traffic were segmented in the enterprise network using VLANs. At the end of the performance test, it was verified that the network devices continued to operate successfully. The telephony features verified to operate correctly included attended/unattended transfer, conference call participation, conference call add/drop, multiple call appearances, caller ID operation, call forwarding unconditional, call forwarding on busy, call Park, call pick-up, bridged call appearances, voic , Message Waiting Indicator (MWI), and hold and return from hold. Serviceability testing was conducted to verify the ability of the Avaya/ProCurve VoIP solution to recover from adverse conditions, such as power cycling network devices and disconnecting cables between the LAN interfaces. In all cases, the ability to recover after the network normalized was verified Support For technical support on ProCurve products, consult the support pages at: 2 of 23

3 2. Reference Configuration The configuration in Figure 1 shows a single site converged VoIP and data network with multiple closets and labs configured with link aggregation, rapid spanning tree, load balancing and OSPF. For compliance testing, a centralized corporate DHCP server was used. To better manage the different traffic types, the voice and data traffic were separated onto different VLANs Control Room The control room consisted of a ProCurve 5406zl Switch, Avaya IP Office, one Avaya 1616 IP Telephone running Avaya one-x Deskphone Value Edition on VLAN Voice1, one Avaya 5610SW IP Telephone on VLAN Voice1, Avaya IP Office Manager running on a HP Proliant Server and one Corporate DHCP/File server. The corporate site provided a DHCP/File server for assigning IP network parameters and to download settings to the Avaya IP telephones. The ProCurve 5406zl Switch supplied Power over Ethernet (PoE) power for the Avaya IP telephones and was configured to support link aggregation, rapid spanning tree, load balancing, VLANs, enforce QoS policies, and OSPF with the peer ProCurve switches Lab-A Lab-A consisted of a ProCurve 3500yl-PWR Switch, one Avaya 1616 IP Telephone running Avaya one-x Deskphone Value Edition on VLAN Voice2, one Avaya 5610SW IP Telephone on VLAN Voice2 and a PC on Datavlan2.

20 9. General Test Approach and Test Results 9.1. Test Approach All feature functionality test cases were performed manually. The general test approach entailed verifying the following: LAN connectivity between the Avaya and ProCurve products Registration of Avaya telephones with Avaya IP Office Verification of the DHCP relay configuration VoIP calls over Layer 2 and Layer 3 connections Inter-office calls using G.711 mu-law & G.729 codecs Verifying that QoS directed the voice signaling and voice media to the higher priority egress queue based on the packets DSCP value. Verifying voic and MWI work properly. Features Tested: attended/unattended transfer, conference call participation, conference call add/drop, multiple call appearances, caller ID operation, call forwarding unconditional, call forwarding on busy, call Park, call pick-up, bridged call appearances The performance tests were performed by over subscribing the lines with low priority data and verifying that the prioritization of VoIP traffic and voice was achieved when calls are routed over all of the LAN interfaces Test Results All feature functionality, serviceability, and performance test cases passed. The ProCurve implementation did prioritization of VoIP traffic and yielded good voice quality with no calls being lost. The Avaya/ProCurve solution was successfully verified through performance and serviceability testing. 20 of 23

21 10. Verification Steps This section provides the steps for verifying end-to-end network connectivity and QoS in the field from the perspective of the ProCurve 5406zl Switch. In general, the verification steps include: Verify the DHCP relay is functioning by confirming that the all IP telephones from all locations receive their IP addresses from the DHCP server connected to the ProCurve 5406zl Switch. Place calls between Labs and Closets for each Avaya IP Telephone. 11. Conclusion These Application Notes describe the configuration steps for integrating ProCurve Switches with an Avaya telephony infrastructure. For the configuration described in these Application Notes, the ProCurve switches were responsible for enforcing QoS using Layer 3 Differentiated Services and Layer 2 (802.1p) as well as link aggregation, rapid spanning tree, load balancing and OSPF. Avaya IP Office delivered the voice traffic to the routers for transmission over the LAN together with data traffic. Prioritization of VoIP traffic and good voice quality was successfully achieved in the Avaya/ProCurve configuration described herein. 21 of 23
